I think the USN are waiting for increment 2 of the LRSM (to mature the tech and before giving it more production volume on their surface fleet). The AGM-158C LRASM achieved operational capability with the US Air Force B-1B and the US Navy FA-18. A single USAF B-1B Lancer can carry and deploy up to 24 LRASM, to provide interim support naval strike operations in the Indo-Pacific, should the need arise. The Americans are not offering the LRSM for FMS sale, at this time — but may do so in a few years.
The Harpoon is in US Navy inventory and certified for use in the P-8A and P-8I— this order will also encourage other Harpoon users to upgrade their older missile stock.
Agreed , and the budget reflects a very sharp increase in LRASM purchases as well as new speakers for the maritime strike TLAM and new purchases for the NSM
